Our research is in the areas of hematopoietic cell transplantation, achievement of graft-versus-leukemia effects without GVHD, organ allograft tolerance induction and xenotransplantation. My research program aims to utilize bone marrow transplantation as immunotherapy to achieve graft-versus-tumor effects while avoiding the common complication of such transplants, graft-versus-host disease. Our laboratory studies in this area have led to novel approaches that have been evaluated in clinical trials. Another major area has been to utilize bone marrow transplantation for the induction of transplantation tolerance, both to organs from the same species (allografts) and from other species (xenografts). Our laboratory has worked toward the development of clinically feasible, non-toxic methods of re-educating the T cell, B cell and NK cell components of the immune system to accept allografts and xenografts without requiring long-term immunosuppressive therapy. Our work has also extended into the area of xenogeneic thymic transplantation as an approach to tolerance induction, and into the mechanisms by which non-myeloablative induction of mixed chimerism reverses the autoimmunity of Type 1 diabetes.
